yeah as long as engine is running ok and isn't leaking oil or blowing smoke it will pass,
main thing they will check is safety items,
suspension,
brakes,
seatbelts,
windows must work,
heater must work for demisting windows
and basically that your chassis isnt cracked or twisted or rusted out..
Then Of course the basics
tyres,
lights and
windscreen must be in good nick as well and make sure all fluids are topped up..
Other than that just everything is bolted on tight
